Please let us know if the beta works for you.
Royal TSX 4.1.2 has officially been released and includes the mentioned fix.
Perfect ! Thanks felix.
This issue is back in version 4.2.1
Since yesterday (update ?) I have this error when I tried to open a 1password vault.
An error occurred while loading a 1Password vault. (Failed to load 1Password libraries. Please ensure that 1Password is installed in its default location. If the application is installed in its default location but you still see this error, the installed version of 1Password might not be compatible with Royal TSX.)
An idea ?
